(A) Growth of Lb. plantarum NCDO 1752 (black lines with circles) and Lb. plantarum WCFS1 (red lines with triangles) in CDM (solid lines, closed symbols) or CDM + 5 μM riboflavin (dashed lines, open symbols) (B) Amplification of the region from lp_1345 to the C terminal of ribB from Lb. plantarum strains chromosomal DNA. Lane 1: Molecular weight marker; Lane 2: Lb. plantarum WCFS1; Lane 3: Lb. plantarum NCDO 1752; Lane 4: negative control (H2O). The size of the marker bands are indicated to the left of the picture. (C) Schematic diagram of the deleted region in Lb. plantarum WCFS1 in comparison to Lb. plantarum NCDO 1752.
